What is an MHTML file?

An MHTML file is an archive that contains all the contents of a webpage. It stores the HTML of the webpage, as well as linked resources in the webpage, which may include CSS, JavaScript, images, and audio files. MHTML files are primarily used by web developers to save the current state of a webpage for archival purposes.

MHTML stands for MIME encapsulation of aggregate HTML documents, or MIME HTML. The files are typically saved by a web browser from an .HTML file and are encoded with .MIME encoding.

You can open MHTML files using various web browsers, including Internet Explorer and Chrome, whether you are online or offline. However, MHTML files saved in one web browser may appear differently when opened in another web browser because there is no standardized MHTML format utilized among all browsers.

Programs other than web browsers can also open MHTML web archives. You can use Microsoft Word, Kingsoft Writer, and WizBrother WizHtmlEditor to open the archives.

MHTML files may be saved as .MHT files, although the .mhtml file extension is more commonly used. The .mhtml extension may also be renamed as .eml and opened as an .EML file instead of an MHTML file.

NOTE: Files with the .mhtml extension are often utilized by cybercriminals to distribute dangerous malware so you should verify the source you received the MHTML file from before opening it.
